Hi,
I recently upgraded from 3.7.4 to james 3.8 .
The server reports warnings like below
"[WARN ] o.a.j.PeriodicalHealthChecks - DEGRADED: EventDeadLettersHealthCheck :
EventDeadLetters contain events. This might indicate transient failure on event
processing”
When I try to see the details of the events using the webadmin API "curl -XGET
http: //ip:port/events/deadLetter/groups" I get the following error as a
response
{
"statusCode": 500,
"type": "ServerError",
"message": "WebAdmin encountered an unexpected internal error",
"details": null
}
From the java trace I cannot understand why it's trying to use elasticsearch
when this is a new opensearch installation.
